Abstract
TúNEL DE PISO DUPLO. A presente invenção refere-se a um túnel de piso duplo onde é um túnel rodoviário de secção circular (1), com dois sentidos de tráfego separados, caracterizado por possuir duas lajes (2) (3), uma colocada sensivelmente a meia altura do túnel e a outra colocada um pouco acima da base do túnel, de modo a formar três galerias sobrepostas, isoladas e independentes: duas galerias rodoviarãas idênticas (4) (5) , uma para cada sentido de tráfego, e uma galeria de serviço (6), na base. As lajes (2) (3) dispõem de aberturas (7), dispostos junto da parede circular do túnel (1), de um ou dos dois lados, regularmente espaçadas e protegidas por disposirivos corta-fogo tipo caixa fechada (8), os quais estão ligados entre si através de galerias de acesso vertical fechadas (10), para permirir a passagem em segurança de pessoas entre as galerias rodoviárias (4) (5) e a galeria de serviço (6), em caso de acidente ou de incêndio no túnel. A galeria de serviço (6) dispõe de veículos de emergência tipo "vai-vem" (9), que podem circular pendurados da Laje inferior (3) , para permitir o acesso fácil ao local ou a evacuação de pessoas, em caso de acidente ou de incêndio no túnel.DOUBLE FLOOR TUNNEL. The present invention relates to a double-deck tunnel where it is a circular tunnel road (1), with two separate traffic directions, characterized by having two slabs (2) (3), one placed approximately halfway up the tunnel and the other placed just above the base of the tunnel, in order to form three overlapping, isolated and independent galleries: two identical road galleries (4) (5), one for each direction of traffic, and a service gallery (6 ) at the base. The slabs (2) (3) have openings (7), arranged close to the circular wall of the tunnel (1), on one or both sides, regularly spaced and protected by closed box fire break devices (8), the which are connected to each other via closed vertical access galleries (10), to allow the safe passage of people between the road galleries (4) (5) and the service gallery (6) in the event of an accident or fire in the tunnel. The service gallery (6) has emergency shuttle vehicles (9), which can be hung from the lower slab (3), to allow easy access to the site or the evacuation of people in the event of an accident or fire in the tunnel.

Relatório Descritivo da Patente de Invenção "TÚNELDE PISO DUPLO"Patent Descriptive Report "DOUBLE FLOOR TUNNEL"
A TÉCNICA ANTERIORTHE PREVIOUS TECHNIQUE
A construção de túneis rodoviários com recurso amáquinas tuneladoras é uma solução cada vez mais usada, tanto porrazões econômicas, como ambientais. Com esta técnica, a referidamáquina escava a terra e coloca aduelas prefabricadas, que passama formar a parede do túnel, que fica com forma circular.The construction of road tunnels using tunneling machines is an increasingly used solution for both economic and environmental reasons. With this technique, the machine digs the earth and places prefabricated staves, which form the tunnel wall, which becomes circular in shape.
Posteriormente é colocado um enchimento na base do túnel, de modoa criar uma plataforma para a circulação dos veículos automóveis,com os dois sentidos de tráfego colocados lado a lado.Subsequently, a filler is placed at the base of the tunnel to create a platform for the movement of motor vehicles, with both directions of traffic placed side by side.
Em túneis com duas ou mais vias em cada sentido, odiâmetro necessário é incomportável para as tuneladorasexistentes. Além disso, no caso de túneis extensos, por razõesde segurança, a solução é também problemática, sendo em geralnecessário construir dois túneis separados, um para cada sentidode tráfego. Será ainda necessário construir galerias e poços deevacuação, para permitir o acesso ao local e a evacuação depessoas, em caso de acidente ou de incêndio num dos túneis.In tunnels with two or more ways in each direction, the required diameter is unbearable for existing tunneling machines. In addition, for long tunnels, for security reasons, the solution is also problematic, and it is usually necessary to build two separate tunnels, one for each traffic direction. It will also be necessary to build galleries and evacuation wells to allow access to the site and evacuation of people in the event of an accident or fire in one of the tunnels.
0 documento W02004094785A refere um túnel circular comduas galerias rodoviárias independentes, em dois níveis, mas estassão muito diferentes, sendo sempre necessário construir um outrotúnel. 0 documento EP1191186A1 refere um túnel circular com doisníveis, em que existe uma parede de separação dos sentidos detráfego, mas cada um permite apenas uma via em cada sentido. Alémdisso, o nível superior permite apenas tráfego de veículosligeiros.Document W02004094785A refers to a circular tunnel with two independent road galleries on two levels, but they are very different, and it is always necessary to build another tunnel. EP1191186A1 discloses a two-level circular tunnel in which there is a traffic separation wall, but each allows only one way in each direction. In addition, the upper level allows only light vehicle traffic.
DOMÍNIO TÉCNICO DA INVENÇÃOTECHNICAL FIELD OF THE INVENTION
0 presente invento constitui uma solução inovadora para arealização de túneis rodoviários de secção circular, com doissentidos de tráfego, permitindo a criação de duas galeriasrodoviárias independentes e idênticas, comportando todo o tipo detráfego, e uma galeria de serviço, para acesso fácil ao local dosinistro e a evacuação de pessoas, em caso de acidente ou deincêndio no túnel.The present invention is an innovative solution for the realization of traffic-free circular section road tunnels, allowing the creation of two independent and identical road galleries with all types of traffic and a service gallery for easy access to the location of the evacuation of persons in the event of an accident or fire in the tunnel.

DESCRIÇÃO PORMENORIZADA DA INVENÇÃODETAILED DESCRIPTION OF THE INVENTION
A máquina tuneladora escava a terra e coloca aduelasprefabricadas, que são gateadas umas às outras, passando aformar a parede exterior do túnel (1), que fica circular.The tunneling machine digs the ground and places prefabricated staves, which are triggered together, forming the circular outer wall of the tunnel (1).
Dentro do túnel são posteriormente executadas duas lajes (2) (3) , a toda a largura, uma colocada sensivelmente a meiaaltura do túnel e a outra colocada um pouco acima da base dotúnel, de modo a formar três galerias sobrepostas, isoladas eindependentes: duas galerias rodoviárias idênticas (4) (5), umapara cada sentido de tráfego, e uma galeria de serviço (6), na base.Within the tunnel two slabs (2) (3) are subsequently made, the full width, one placed approximately half the height of the tunnel and the other placed just above the base of the tunnel, to form three isolated and independent overlapping galleries: two identical road galleries (4) (5), one for each traffic direction, and a service gallery (6) at the base.
Nas lajes (2) (3) são executadas aberturas (7),dispostas junto da parede circular do túnel (1), de um ou dosdois lados, regularmente espaçadas e protegidas pordispositivos corta-fogo tipo caixa fechada (8), providos de portas de emergência. Os dispositivos corta-fogo (8) de cadalado estão ligados entre si através de galerias de acessovertical fechadas (10), providas de escadas interiores, parapermitir a passagem em segurança de pessoas entre as galeriasrodoviárias (4) (5) e a galeria de serviço (6), em caso deacidente ou de incêndio no túnel. As galerias de acessovertical (10) poderão ser alargadas através da paredecircular do túnel (1).Slabs (2) (3) are provided with openings (7) arranged near the circular tunnel wall (1) on one or both sides, regularly spaced and protected by closed box fire devices (8), provided with doors of emergency. The fire stop devices (8) are connected to each other via closed access-vertical galleries (10), provided with interior staircases, to enable the safe passage of persons between the road galleries (4) (5) and the service gallery (6) in the event of a tunnel accident or fire. The acessvertical galleries (10) can be widened through the tunnel wall (1).
Na galeria de serviço (6), são instalados veículos deemergência tipo "vai-vém" (9), que podem circular pendurados dalaje inferior (3), para permitir o acesso fácil ao local eevacuação de pessoas, em caso de acidente ou de incêndio no túnelIn the service gallery (6), emergency shuttle vehicles (9) are installed which can be hung from the lower floor (3) to allow easy access to the site and evacuation of people in the event of an accident or fire. in the tunnel
